摘要
文章对国内外星载超光谱成像系统的应用状况进行了归纳,重点对其应用特点和关键技术进行了总结。在此基础上阐述了基于小卫星平台的超光谱成像系统的技术优势,探讨了利用小卫星姿轨机动灵活和可组成分离异构星座的特点,来实现星载超光谱系统对地实时成像以及解决海量数据处理和传输等关键问题的可行性,并着重对研制适应小卫星平台的集约型超过光谱成像载荷关键技术进行了分析。为建立星载对地"光学实时光谱识别系统"(ORASIS)提供参考。
Firstly,the condition of space-borne imaging system was summarized, and particularly the application characteristic and key technology were described. According to this, the idea concerning hyper-spectral imaging system based on micro-satellites was brought forward, moreover, it discussed how to actualize real-time imaging and solve the problem of data compression and transmission utilizing agile attitude and orbit and network of micro-satellites with separated and different structure. Then the key technology of developing miniaturized hyper-spectral imaging system was analyzed. It would give some reference to the foundation of ORASIS.
